Lately i've been getting heart thumps and flutters or what feels like an irregular heartbeat every day. It will feel like slow slow fastfastfast slow fastfastfast....Or some other combination. It never seems steady. And if i'm exerting myself in any way my heart beats so hard and upon inhalation it gets super fast and exhalation a lot slower beat. Sometimes it feels like my heart is actually causing my body to jerk from beating so hard, and I get dizzy sometimes. Also, almost a lump feeling in my throat or the feeling of a little beat in my throat and sometimes breathing in makes me have to cough and it feels like my heart is causing it or something. Has anyone else had anything similar? I've been diagnosed w/ anxiety disorder before, but I don't believe many docs because you always hear of people dying because doctors don't do thier jobs and don't pay attention to the patient's concerns. I'm afraid of a heart condition or arrhythmia. I've had heart xrays, chest ct, ekgs and tests for blood disorders. All have been okay. Would it have been found already? Or what tests should I ask for to rule out a condition or arrhythmia?
